Abstract: A data link control method including receiving a message (30) for transmission over a cable communications system. The method determines a number of octets in the message (30). When the number of octets is less than or equal to a predetermined number of octets, the method sets a frame length (44) equal to the number of octets and transmits a frame (180) containing the message (30). When the number of octets is greater than the predetermined number, the messages (30) is segmented (32-42), each segment being identified in order with respect to the other segments. The method thereby provides for graceful communications resumption when the transmission of a message is interrupted before completion.

Abstract: A control unit (102) efficiently decodes burst signal transmissions in a TDMA-based telecommunication system (100) by decimating down the number of samples requiring processing during symbol detection. The control unit (102) includes a sampling receiver (304) that inputs burst signals from cable access units, converts them to a pair of baseband quadrature signals, I and Q. The sampling receiver (304) also includes an A/D converter (314) that samples the I and Q signals at preferably four times the symbol rate. A digital signal processor circuit (306) produces a timing error signal for substantially all of the samples. The digital processor circuit (306) also accumulates a timing error sum for each of the four samples. The processor circuit (306) selects the optimum sample as the sample between the samples having the largest positive and negative error sums. The processor circuit (306) also includes a pi /4-DQPSK differential detector that processes the optimum sample of each symbol for symbol detection.

Abstract: A decoder (215) implemented in a receiver of a wireless communication system employs an improved method and apparatus for decoding an encoded signal. The receiver sums the energy values (156A, 156B, ...156N) from a plurality of fingers within to produce an aggregate energy value (166). From the aggregate energy value (166), a set of log-likelihood values (207) are generated with a non-linear function generator (205) before being deinterleaved by a deinterleaver (210). The deinterleaved values (213) are input to the decoder (215) which estimates the original signal (178) by incorporating path histories of bits in the estimation of subsequent, related bits. Use of the path histories of bits improves the estimates of the original signal (178), which translates into an increase in the sensitivity of the receiver.

Abstract: A computing element (200) in a computational array includes a memory bypass system which performs in a single clock cycle a calculation that requires the result of a previous calculation performed in a previous clock cycle. The computing element has a computational unit (210) which performs calculations and a result memory (240) which stores the results of the calculations. The memory bypass method and system bypasses the result memory (240) when it determines that the result of a calculation is needed as an input to the next calculation to be performed, and provides the result of the calculation directly to the computational unit (210) to perform the next calculation. Otherwise, when the result is not needed as the input in the next calculation, the memory bypass method and system reads the input for the next calculation from the result memory (240).

Abstract: A telecommunications system (100) includes a service provider (200) providing a plurality of services to a plurality of terminals (400, 401, 402). A controller (300) having a user identifier stored therein can be associated with a reader in the terminal for reading the user identifier. A selector in the terminal (400) selects one or more of the plurality of services to be associated with the user identifier. A transmitter transmits to the service provider (200) user-service information corresponding to the user identifier and information as to the selected services. The service provider (200) receives the user-service information and determines from which service provision area the user-service information was transmitted. A service provision controller determines that a particular service is to be provided to the user and a determining means determines whether the particular service is included in the first set of selected services. A paging message having paging information corresponding to the user-service information is then transmitted to the service provision area. The terminal (400) receives that paging message and responds to the service provider (200) if it can accept the service.
